TAKE-DOWN APPARATUS FOR GLASS CYLINDERS.

Specification of Letters Patent.

Patented June 9, 1908.

Application filed'May 10,1906; Serial No. 316,049.

Pennsylvania, have invented certain new and useful Take-Down Aj) aratus for Glass Cylinders, of which the 0 lowing is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a side elevation showing one form of apparatus constructed in accordance with my invention; Fig. 2'is an enlarged detail view of the traveling grip frame; Figs. 3 and 4 are detail views of the rips in different positions; Fig. 5 is a to) plan view of the drum mechanism; F ig. 6 is a side elevation of "the take-down drum; and Fig. 7 is a partial \to that shown in side elevation showing a modified form.

My invention relates to the taking down of glass cylinders which are drawn upwardly from a batii. j

The object oi the invention isto rovide an effective apparatus which wil avoid breakage and the use of skilled labor, by which the cylinder may be engaged in vertical position, and then carried sidewise and lowered u )on a suitable horse or support.

in the drawings, 2 represents a stationary inclined track, which extends from a mint adjacent to the drawing mechanism iindicated by the cage and blow pipe 41), and on which travels the triangular frame 3, having trolleys 4, 4 moving in suitable recesses or double tracks 0111 the su port 2. These tracks are so arranged as to iiold the frame at a fixed angle to the track during the travel of the frame. The side members 3, 3 oi the triangular frame may be lixed relative to each other; but I prefer to arrange them so that the shape of the triangle may be changed to assist in lowering the cylinder when desired.

In the form shown in Figs. 1 and 2, the member-3 is oi telescopic form, the portion 3 being a rod which slides withinthe other tubular portion, and is provided with a rack engaged by a pinion on a shaft 5 having handwheels 6. The shalt 5 is mounted on a collar 7 and the pinion projects through a slot in the tubular portion, thus allowing the length of the arm 4 to be adjusted. By turning the hand wheel, the frame members may be moved from the position shown in full lines other positions. The frame members 3, 3' at their lower apex are provided with a bearotted lines in Fig. 2, or into l ing 8 in which is pivoted the rack bar 9, (Fig. 4) which slides through a casting 10 in which are secured the adjacent ends of the registering rods 11. V The teeth of the double rack bar engage pinion s 12 secured on longitudinal' rods 13, at the ends of which are provided the gripping arms 14. The shafts 13 turn in bearings secured in forks 15 (Fig. 3) projecting from the upper and lower ends of rods 11. The rods 13 are continued downwardly below the lower grips, and to these extensions are secured levers 16, one of which is provided with a link 17 having slots arranged to en gage a pin u on the other lever. A spring 1 8 is connecte( to short lever' arms 19 u on the rods 13, the s )ring being so arrange that it will tend to hold the grips in 0 en. and in closed position. Fig. 3 snows t e parts in' open position, while Fig. 4 .shows them in c osed position. Itwill be noted that when the glass cylinder is in inclined or horizontal position, the gravity effect through the rack and pinion mechanism will also increase the hold of the grips TIPOIL the cylinder. This is the function of this rack and, pinion mechanism. k

In order to prevent oscillation or improper swinging of the cylinder during removal and lowering, I. preferably provide a friction brake mechanism. This is especially desir able when the neck or upper portion of the cylinder breaks away from the bait or blowpipe during lowering. in the form shown (Fig. 2), this brake device consists of asector 20, which is engaged by a leaf-spring 2t) on one of the arms oi the triangular frame. The leaf-spring bears upon the sector with sufficient Jressurc to dampen the swinging of the cylin er.

The take-down frame may be moved along its track, either by gravity orpositively. I

prefer the positive movement, as thereby any sticking or checking of its movement is obviated, in the form shown, a cord 21 extends from the tithe-down frame itup to a winding drum 22. The upper end of the cord 21 winds about one side of this drum, while to the other side is secured the cord 23 which extends over the clmnterweighted tightening pulley 24, and thence over lpullcys 25 and 26 and back to the frame tow iich its end is secured. The winding drum 22 is pretci' abl'y sha )ed as shown in Figs .3 and (i. It is made in duplicate halves with a helical groove on each half of increasing pitch. .\s

the cord 21 winds up on one portion, the cord 23 unwinds on the other portion, while the belt tightener device 24 (Fi 1) compen sates for varying amounts of a toothed wheel 27 on the shaft of the winding drum intermeshes with the pinion 28 on the shaft of an electric motor 29. The connections for the electric motor extend to a hand-controlled switch device 30, which is at the operators pulpit. This circuit is also rovide with a circuit breaker 31, which is oeated at the upper end of the stationary track and is moved in one direction by contact of the trian ular frame, while it is moved in the o posite direction by. the cord connecend of the track will 0 en the circuit to mo tor 29 and close the circuit to themagnetic clutch 36, thus locking the two winding drums together. The operator will then lower the cage, and at the same time posi-' tively move the take-down frame along its track. The blow-pipe 41 is pivoted at 42, and as the point 42 reaches, the ositions marked a, b, c, d, e and f, the pivota point 8 of the take-down frame passes'throughthe positions (if, b, c, d, and f At the posi-' tion f the frame strikes the lever 33, thus releasing the magnetic clutch. 36 and completing the circuit for the motor 29. The operator at this point lifts the blow-pipe out of its sup orting hooks, and further movement of the rame along the track may be either by gravity or the operator may throw in the motor 29 and positively move the frame through the remainder of its travel; The 0 erator can then lower the cylinder upon t 1e horse shown at 43 by manually changing the sha e of the triangular frame, as above described, or the cylinder may be lowered by a differentially inclined portion of the track which may be eitherstationary or pivoted. If pivoted, the track section may be either moved manually or automatically.

In the form shown, .the track section 2 is pivoted to the main track section, and provided with an adjustable counterweight 44. When the rear trolley of the frame enters this pivoted portion of the track the weight of the cylinder will act in opposition to the weight 44 and gradually tilt the, track into the position shown in F1 1, the glass cylinder thus being lowere upon the horse.

When the operator then disengages the grips ck. A large a number 0 by the link mechanism, the weight'44 will return the pivoted track section to its normal csition inline with the stationary track, thereby lifting the grips away from the cylinder. The operator may then draw the take-down frame to an intermediate position in the track by use of the motor 29 where it Will remain until the next cylinder is drawn. After the next cylinder is drawn, he then moves the frame forwardly and upwardly into the position shown in Fig. 1, by

means of the motor 29 and engages the eylinder with the grips, after which the operation is repeated as above described.

In Fig.7 I show a modified form of the apparatus', which provides one take-down device for a series of. drawingmachines. In this form, 45 represent tracks carried on suitable supports and extending in front of drawing machines. On these tracks travel the trolleys 46 carrying the hangers 47, on which the stationary track 2 is mounted. In this form the motor 29 is carried on the stationary track, and is supplied with current through a trolley device 48. The drum 22 may be the same as before, and have any suitable mechanical connection to the motor 29. In this form also,

I show another construction of the takedown frame. In this case the frame members are pivoted at their ends and a link 49 extends framemember to a collar 50, which slides on the lower frame member. The link 49 is provided with a handle extension 51, by which the frame may be drawn into diifer-, ent shapes, one ofwhichis shown at the rom the top pivot of the upper right-handof Fig. 7 in dotted lines. 52 indi- 'cates a hook by which the parts maybe locked in the position shown in full lines.

In case where the take-down mechanism is movable along the pets to serve a series of.

drawing frames, the [connections between the winding drum of the take-down device and the hoisting drums for the drawing frames, is an electrical one. ,T The operations in this case are substantially the same asin the first ,form.

The advantages of my inventionwill be apparent to those skilled in the art. The operations are simple and easily controlled,

The movements in the positive and under comp ete control. Mistakes on the part of the operator are avoided, since the relative movements must take greatly reduced and all danger of injury to the workmen is avoided.

and breakage of the glass is greatly lessened. 1

referred form are jacent to the Many variations may be made in the form and arrangement of the frame, track, the grips, 62c, without departing from my inven tion.
